Introduction The power battery system is the core driving force of electric vehicles. It consists of a battery module, electrical system, thermal management system, battery management system, housing and other parts. The main function of the shell is to load and protect the battery module, which needs to meet mechanical requirements such as strength, stiffness …
Introduction Lithium-ion batteries consisting of LiCoO2 and graphite are popular worldwide as power sources for mobile phones, laptop computers, and other electronic devices. Graphite and LiCoO2 are called lithium insertion materials. In other words, the lithium-ion battery consists of two lithium insertion materials. The combination of two lithium insertion materials is essential for the basic functionality of the …
Introduction Overcharge is one of the difficult to pass in the current lithium battery safety test, so it is necessary to understand the overcharge mechanism and the current measures to prevent overcharge. Figure 1 shows the voltage and temperature curve of the NCM+LMO/Gr system battery when it is overcharged. The maximum voltage is reached at …

Introduction Electric car often has the fault two: motor spinning when stopped (battery vulcanization):1. The battery voltage in the state of under-voltage critical will appear when turning and stopping,2. Poor contact with the battery connector will also occur this fault,3. The speed control turns the line to break the state and the brake power off switch is faulty. Battery …
Introduction The full name of the battery is State of Charge, also known as the residual power. It represents the ratio of the remaining capacity of the lithium batteries after being used for a period of time or for a long time to the capacity of the full charging state, which is often expressed as …
